In fact, Industrial growth moves hand in hand with the growth of the measurement of

Science and Technology. Therefore, it is highly essential for Electrical Students to

study about the measurement of various Electrical Parameters in a system and the

construction and working of different Instruments used in measurement of such

parameters.

RATIONALE

Energy conservation is the effort made to reduce the consumption of energy by using

less of an energy service. Energy can be conserved by reducing wastage and losses,

improving efficiency through technological upgrades and improved operation and

maintenance. Energy Audit is the key to a systematic approach for decision-making in the

area of energy management. The effective use of energy to maximize profits (minimize costs)

and enhance competitive positions, it is necessary to conserve energy. Hence it is necessary

to study energy auditing methods and energy saving opportunities in electrical system.

OBJECTIVES

At the end of the Semester, Students will be able to:

✓ Explain necessity and importance of Energy Conservation

✓ Explain the goal with energy conservation techniques is to reduce demand,

protect supplies, develop and use Alternative Energy Sources.

✓ Explain the energy efficient technologies in Electrical System

✓ Explain the Periodic maintenance of Electrical Systems.

✓ Explain Technical losses and commercial losses in installation Systems.

✓ Explain How to product output or to lower operating costs.

✓ Discuss about Energy Conservation Equipment
